Been playing this game over the free weekend for the first time, and brought it for my brother way back at the beginning years ago for Christmas.
I think it's getting there but dying of thirst or hunger twice before the sun rises is ridiculous and unrealistic. I would make it so it takes 2-3 days to die from thirst, with it giving some sort of an effect to the stamina over time, not as rapid as it currently is.
This one thing really holds the game back for a lot of people I know, you can easily sit there and say NOOBS but that isn't going to make the game a success.
Also, I'd like to add I agree more loot is very much needed, more consumables out in the wild too.
